The research work presented in this paper aims at evaluating the potential of the direct wave
of radar ground-coupled antennas for the on site physical characterization of concrete.
According to studies highlighting the ability of radar reflected waves to characterize
concrete, the potential of the direct wave is studied by systematic comparison of direct and
reflected wave attenuations. Among the various features of electromagnetic waves
propagating through concrete, attenuation is the most sensitive to moisture and chloride …
